This volume is a comprehensive overview of the scientific discipline that studies psychological and biological processes and behavior in humans and other animals. It features chapters on the history of the field, the thought process, memory, theories of personality, and key figures—such as William James, Sigmund Freud, Jean Piaget, B. F. Skinner, and Daniel Kahneman—who helped shape the field. The difference between clinical psychology and the growing science of mind, brain, and social behavior is discussed, as are several subfields of psychology. A glossary offers a quick reference for definitions of key terms in the field. This comprehensive guide is the perfect introduction for students, in particular those studying the development of the field.
